Be it known that 1, WILLIAM J. MILLER,

a citizen of the United States, residing; at

Delaware,-in the county of Delaware'and State of Ohi0,-have inventedcertain new and useful Improvements in Supports for Mail Boxes, of whichthe followlng Qis a specification.

This invent on relates to supports formallboxes used on rural routes;and 1t consists in the novel construction and combination view showing.the cranearni in its normal- 3 is'a cross-section through position.-Fig.

taken on the line 8 3 inFig.

the cranearm,

1, and showing a portion of the post. Fig.

4 is a plan view of the top of the crane post showing the brackets insection.

The lower or main part 6 of the crane post is arranged vertically, andis secured in the,

ground in any approved way, and position, and it is of any approvedheight. When the crane arm is mounted to swing around the post, theupper part 7 or cap of the post is provided with a stem 8 which isjournaled in the main part of the post, and is provided with acircumferential groove 9. A screw is screwed into the outer part of thepost and engages with the groove 9 so that the parts of the post areheld in engagement. When the part '7 is not intended to rotate, thescrew 10 can be used .to hold it stationary.

A telescopic crane arm comprising an outer tubular part 12, and an innertubular part 14:, is pivoted by a' horizontal pivot pin 15 to the upperend portion of the crane post, brackets 16 being secured to the outerpart 12 of the crane arm and pivoted on the pin 15.

The brackets 16 are secured to the outer end portion of the outer andnon-slidable part 12, but they need not be arranged at its extreme end..The position of these brackets is adjusted so that when the arm istilted horizontal and extended the outer part 12 will counterbalance theinner part 14- and the mail box to a predetermine extent. The

brackets 16 project laterally of the crane arm, andtheir pivot pin .15is arranged crosswise of and over the axis of the vertical crane post 6.i

-, Both tubular parts are rectangular in cross-section, and the innerpart is arranged to slide. freely in the outer part upon small rollersl7 arranged along one side of the outer part at suitable intervals.Theyinner end of the inner part 14 is closed by a plug.

18, .anda small roller 19 isjournaled on the oth'er side of it from therollers 17, andprojects partway through aslot in'its-side so that itruns onthe opposite side of the outer part of the arm from the rollers17. A small roller or' stop 20 is also-mounted at the open end portionof the outer part in .thepath of the roller 19 to; prevent the'innerpart from being wholly withdrawn from the outer part and to assist it insliding. a

Themail'box24 is secured to one end of the inner part; 14 of the cranearm, andiis of any approved construction, andhas one ormore doorsofletter openings at any suitable points or locations. i

The other, end crane arm is closed by a plug provided with a buifer 26,which may be of India rubber. The plug 18 of the inner part strikesagainst the buffer when the arm is tilted to the position shown in Fig.2. V

A collar 80 is secured to the upper part of the crane post, and when theupper part is not rotative this collar can be secured to the main partof the post. 1 Two inclined guide arms 31 are provided, and areconnected to lugs 32 on the collar at their lower ends by a pin '33.These guide arms are retained at an angle to the vertical by links 34connected to their middle parts by f the outer part 12 of a,

pins 35, and'to the post by the pivot pin 15 of the brackets.

A roller 36 is journaled between the upper end portions of the guidearms 31 for the inner part l l of the crane arm to run on, and to takethe weight of the mail box when loaded. This roller or rest is arrangedabove 7 Fig. 2. When the mail carrier comes along in his cart, hecatches hold of the mail box with a long hook, and tilts it over anddraws said crane arm being arranged to tilt over the top of the cranepost',-a mail box carried by the slidable part of the crane arm, and arest for the crane arm when tilted, said rest being'supported by thecrane post and arranged above the level of the pivot of the crane arm.

2. A support for a-mail boX' asset forth in claim 1, the said crane armbeing provided with antifriction bearing devices between its outer andinner parts to permit the slidable part to slide freely.

3. A vertical crane post" provided with a rotary upper part, atelescopic crane arm pivotedto the-said upper part and arranged totiltover the top of the crane post, a mail box supported by the slidablepart of the crane arm, a rest for supporting the crane arm when tilted,said rest being supported by thecrane post and rotating. with its upperpart and arranged above the level of the pivot of the crane arm.

4. A vertical cranepost, a telescopic crane arm, brackets secured to andprojecting laterally of the non-slidable part of the crane arm andpivoted to the crane post, said crane arm being arranged to tilt overthe top of the crane post, a mail box carried by the slidable. part ofthe crane arm, and a rest for the crane arm when tilted, said rest being supported by'the crane post and arranged above the level of thepivot of the crane arm.

5. A crane post, a telescopic crane arm comprising an outer tubular partpivoted to the said post and an inner part slidable in the outer part,rollers for the inner part of the crane arm to run on arranged at oneside of the outer part, a roller carried by the said inner part andrunning on theopposite side of the outer part from the said rollers, amail box secured to the said outer.

part, and a rest for supporting the crane arm when tilted carried by thesaid post.

6. A crane post, a telescopic crane arm comprising an outer tubular partpivoted to the said post and an inner, part slidable in the outer part,a mailbox secured to the said outer part, and a rest for supporting thecrane arm when tilted carried by the said post, said restcomprising twoupwardly and.

outwardly inclined guide arms, retaining links, and a roller journaledbetween the upper end portions of the guide arms. In testimony whereof Ihave mixed my signature.
